Kernel versions 2.0.x and 2.2.x introduced quite a bit of changes for kernel
installation. The file Documentation/Changes in the 2.0.x source
tree contains information that you should know when upgrading to either of
these versions. You will most likely need to upgrade several key packages,
such as gcc, libc, and SysVInit, and perhaps alter some system files, so
expect this. Don't panic, though.
